Depending on the climate of a location, HVAC systems may be used to provide heating and cooling. They are also used for ventilation and to improve indoor air quality. A HVAC system may be a single zone system or a full building system. A single zone all-air system can be on or off, and the unit can be adjusted to meet thermal load requirements. The system is controlled by a thermostat.
Thermostats can be conventional, digital, or smart. A smart thermostat is a thermostat that has the capability to detect problems and notify the homeowner. It can also be programmed to trigger different components of an HVAC system. This can improve energy efficiency and reduce overall energy costs. A smart thermostat can also share diagnostic information with a hvac contractor.
The air that passes through the filters is cleaned of airborne particulates. This can include pollen, mold spores, and animal dander. These pollutants can affect the health and well-being of occupants. The filters need to be maintained and checked periodically. Carbon impregnated filters can improve indoor air quality. Some manufacturers also offer partial bypass carbon filters.
A HVAC system may also include humidifiers. A humidifier can help reduce the dew point of the air in the home. Some whole-home dehumidifiers can also lower the dew point. HVAC systems may also include air purifiers and other home comfort products. These products can be added to an HVAC system to provide optimal thermal comfort for occupants.
The system may include ductwork. Ductwork is used to transport air from the indoor units to the outdoor units. Some ducting systems may not be compatible with certain HVAC systems. Depending on the HVAC system, the ductwork may include a supply or return air fan, a preheat coil, a cooling coil, or an air handling unit.
Central air systems includes a mixing box, a preheat coil, and an air handling unit. The air handling unit may include a humidifier and a cooling coil. The air handling unit is usually located near the foundation of a building. The air handling unit can also include an evaporator, a condenser, and a compressor. The equipment may be installed directly into the home or a room.
The components of an HVAC system can vary by the age and design of a building. Selecting the right HVAC system can depend on the building’s age, the climate, and the preferences of the building’s owner or designer. For example, a modern home may require fans and filters. The selection of an HVAC system can also depend on the age of a building or the architect’s preference.
A HVAC system may also have a number of features to benefit school occupants. Some of these features include variable occupancy systems, which can help reduce moisture and control mold. Another feature is an air cleaner that can remove viruses, bacteria, and odors.

Some systems have CO2 sensors that need to be calibrated periodically. Ventilation systems can also be used to provide supplemental exhaust ventilation during renovation activities. This can be a more energy-efficient way to supplement an HVAC system. Operable windows can also provide outside air ventilation.
